Hypochaeris glabra is an annual herb growing a small taproot, a basal rosette of leaves, and one or more thin stems 10–40 cm (4–16 in) tall. The leaves are 2–10 cm (3⁄4–4 in) long, smooth along the edges or with small lobes, and green in color, sometimes with a purplish tint near the veins. Atop the thin, naked stems are flower heads with small overlapping purple-tipped phyllaries and bright yellow ray florets. The fruit is a cylindrical achene with a white pappus almost 1 cm (3⁄8 in) long.[7]
